Whic is the best mod to grind xp? Turbo warzone or Rock N' Rail?
They are both excellent. I say play whichever one you want, or whichever you have better boosts in. Rock n rail games usually last about 4 minutes, so if you have good boosts, that can stack up very quickly. Unfortunately due to the weighted odds Warzone boosts from packs, I have virtually no arena boosts and plenty of Warzone boosts, so turbo is a better option in my situation
Ive played for around an hour and a half and almost got 200.000 xp from just playing rock and rail. Warzone turbo matches last longer and if you dont have the good boosts id go for rock and rail.
